Hello guys

Do you know how I can have this effect in copernicus ? I use it a lot for create flakes effect on products....

You can simply use sops for that.

Put down a grid with 2 rows, 2 columns, scatter some points, stick that into a voronoi fracture, add an enumerate sop, set it to primitives and the attribute name to "index".

Make a copnet, put down a sop import and point it to your grid, stick the output of that into a rasterize geo cop, add an output type ID, and set the name to index.
Done.

Edit: attached a small demo hip.

This is id output of Worley Noise in cops
